UNITED STATES ALEXANDER MASZCZYK, 0F CHICAGO, ILLINOIS.

COMBINATION MACHINE VISE.

Application filed March 23, 1923.

To all whom 'it may concern:

Be it known that I, ALEXANDER MAsZczYK, a citizen of the Unit-ed States,and resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in a CombinationMachine Vise; and I do hereby declare that the following is a full,clear, and exact description thereof.

This invention relates to vises. It comprises a plate adapted to besecured to a machine bed or like support, acylindrical table integraltherewith, a stud carried by the table, and a vise proper, the bed ofwhich is swiveled on the stud and has a guideway therein for thereception of a slide which is movable by a screw to cause a jaw pivotedthereon to approach a jaw fixed to the bed.

The primary object of the invention is the provision of a vise adaptedto be used on milling machines, grinders, drill presses, and the likedevices, which may be conveniently secured to a bed-plate which isadapted to securely retain stock of various shapes. The free jaw may belocked rigid with the slide yand then is disposed parallel to the fixedjaw, or the free jaw may be inclined to receive the fixed jaw so as togrip material of wedge shape. The mounting of the vise bed in the mannerof a turret facilitates the usage of the device in different positionsof adjustment, so that it presents the material wo-rked onadvantageously for the actions of the milling or other machine. The bedmay be secured rigidly to the table, so that a positive and effectivegrip is exerted on the material which is incapable of movement in anydirection.

An object of the invention is the provision of a vise which may be usedfor bending purposes. The movable jaw may be rotated on its pivot topresent a nose towards the fixed jaw, the nose being rounded toJfacilitate the bending operation. If desired, the movable jaw may beremoved entirely and replaced by a roller, as the pivot carried by theslide is adapted fo-r this purpose, so that the bending operation may becarried o-ut with the greatest convenience.

An object of the invention is the provision of a device which may, ifdesired, be used as a jack. The bed may be disposed vertically and themovable jaw may then be used for lifting purposes.

Serial No. 626,997.

l lVith the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the novel construction,combination and arrangement of parts substantially as hereinafterdescribed and more particularly defined by thek appended claims, itbeing understood that such changes in the precise embodiment of theherein disclosed invention may be made as come within the scope of theclaim.

In the accompanying drawing is illustrated one complete example of thephysical embodiment of the present invention constructed according tothe best mode so far devised for the practical application of theprinciples thereof.

Figure 1 is a plan view o-f the device, showing in dotted lines thereversed position of the movable jaw, and indicating by a broken linethe position of' a roller which may be substituted for the movable jaw.

Figure 4 is an end view of the entire mechanism; t Y j Figs. 5,6 and 7are sections on the lines 5-5,6-6, and 7-7 of Fig. 2; and .Y

Fig. 8 is a plan showing the disposal of the jaws with a wedge-shapedpiece of work j therebetween.

In order that the vise may be used to advantage in connection withmilling machines, grinders, drill presses, and the like devices, a plate10 is provided having slots 411--11 therein, adapted to receive boltsfor securement to the bed-plate of the machine.` Suitably secured to thelower face yof plate 10 is a bar 12 which may be disposed in a groove inthe bed-plate. By means of a reduced neck 13 the plate 10 is integrallyconnected with a cylindrical table 14 having a beveled lower side 15.The table is bored toy receive van enlarged portion of the stud 16 and achamber 17 is provided in the plate 10 immediately below the bore. y

The vise proper has a bed 18 provided with an opening 19 receiving thestud 16. The bed is thus swiveled on the table 14 and may be moved toany desired position of rotation about the stud 39. This facilitatesusage of the device with machines of various types, as it is adapted topresent the material in an advantageous position for action by themachine. The bed 18 is provided with llO longitudinal flanges 20-20having holes 2l therein for the reception of hook bolts 22, the heads otwhich are adapted to grip the beveledL lower ace `of table 14. rillienuts 23 on the bolt rest on the flanges. By means of the bolts the visebed may beA secured rigidly in any desired position oi' rotation aboutthe stud and the resulting rigid relan tion of parts makes secure theholdin of the material in position for operation by the niachine inconnection with which the vise may be used. Additional openings 24 arepro vided in the flanges 20-20- li desired, the bolts 22 may be removedand the bed may be used independently oi the table, in which case theholes 24 are useful for the purpose of bolting the vise bed in desiredposition. The vise bed has a longitudinal channel thereinA and a recess2G intersecting the channel. The upper part of the recess is filled byblock 27 threaded to a screw 28 having a squared end 29 by wliichit maybe rotated to travel through the channel. A jaw 30 is formed on one endoi the bed and is secured by screws 3l to a clamping plate 32 havingintersecting gripping grooves 33 in its face. A vertical cavity 34extends from in front of the plate 32 to the top oit table 14. it isusedv for objects which it is desired to dispose vertically for workingpurposes. The work may be inserted into the cavity and disposedconveniently in front oit the gripping plate 32. The vise bed has alongitudinal guideway 35 of inverted 'ln-shape in cross-section intowhich is fitted a slide 36 having at its outer end a dependingprojection 87 in which the screw 28 is secured for rotation by means ofa pin 38 i'itting into an annular groove 37. @ln the rotation of 'thescrew the slide 3G is caused to approach o'r`recedie from iiXed jaw SO,they screw being substantially in threaded relationship with the visebed by means of block 27. Formed integrallyr on the innerend of slide 36is a pivot 39 on which movable jaw 40 is rotatably mounted. A clampingplate 4l is secured to the jaw by means of yscrews 42. A recess isprovided in the upper face of jaw 40 for the reception of a washer 43which is countersunk to receive a screw 44 threaded into pivot 39. Thejaw 40 is providedv at its outer end with a rounded nose 45 having anopening therein inwhich a screw 46 is placed, the screw extending intoslide 36 and rendering jaw 40 rigid therewith.

lNhen screw 4G is in position, the clamping plates 32 and 4l aredisposed in parallel relation. It desired, screw 4G may be removed andthe clamping plate 4l may be disposed at an angle to clamping plate 32as shown in Fig. S. A wedge-shaped piece of work 47 may then be grippedby the jaws. It is apparent, tliere'lfore,^that the material iseiiectively clamped and secured against displacement, irrespective oithe position of the jaws, which are adapted to effectively grip objectsof various shapes.

lf desired, movable jaw 40 may be rotated to dispose the nose 45adjacent to clamping plate 82 as shown in dotted lines in Fig. l. Therounded4 nose may then be used for the purpose oi bending, as the noseand clanip ing plate 34 grip the stock which may be shaped about therounded nose. By removing screw 44 pivot 39 may be utilized forsupporting a roller in the position shown`v by the broken line in Fig.l. The roller also may be used for bending purposes.

rihe vise may be separated yentirely from table 14 and may be used in avertical position, either with or without the table. lt may also be usedas a jack, in which case jaw 40 is operative for lifting vertically.
